LOCOMOTIVE-BED.

Specication of Letters Patent.

Patented Mar. 7, 1916.

l To all whom it may concern.'

Be it known that I, HARRY M. PFLAGERa t. Louis, Missouri, have invented a certain new and useful Improvement in Locomotive- Beds, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it apper tains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates generally to locomotives and more particularly to the bed or frame which is carried by the driving wheels and pony truck, and serves as a support for the body of the locomotive.

The principal object of my invention is to l provide a locomotive bed having separately formed side frames which are substantially of flanged channel shape in cross section, and said side frames being rigidly connected by means of separately formed'cross pieces, such as frame braces, expansion braces, frame filling pieces, pony truck center guide, and other essential parts.

Further objects of my invention are to provide the side frames of the bed with openings which are adapted to receive the journal boxes for the axles which carry the driving wheels, to form integral with the side frames at the sides of said openings, pedestal jaws and to reinforce said jaws and the frame immediately above the openings with integral flanges and ribs, thereby producing a very strong, rigid and substantial structure which, in service, effectually resists all strains and vibration to which it is ordinarily subjected. I'

This application should be considered in connection with a copending application led by me Oct. 27, 1915, Serial No. 58,171.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of a locomotive bed of my improved construction. Fig. 2 is a side elevational view of the bed. Fig. 3 is an enlarged cross sectional view taken approximately on the line 3-3 of Fig. 2. Fig. 4 is an enlarged cross sectional View taken approximately on the line 4 4 of Fig. 2. AFig. 5 is an enlarged cross sectional view taken approximately on the line 5-5 o f F 1g. .2. Fig. 6 is an enlarged cross sectional vlew taken approximately on the line 6-5 ofFig. 2. Fig. 7 is an enlarged cross sectional View taken approximately on the line 77- of Fig. 2.

As illustrated in the accompanying drawings, the bed or frame contemplated by my lnventlon, includes a pair of separate formed side members 10, the main body portion of each of which is substantially of channel shape 1n cross section, and comprising a vertically disposed web 11, an outwardly presented top flange 12, and an outwardly presented bottom flange 13. Depending from the outer edge of top flange 12 is a flange 14 and projecting upwardly from bottom flange 13 1s an integral flange 15. Formed 1n the lower portions of the side members 10 are openlngs 16 which serve as pockets for the journal boxes which receive the driver axles and formed integral with the side frames to the sides of these pockets are pedestal jaws-17.

`T he vertically disposed flanges 15 which project upwardly from the bottom. flanges 1 3 are extended upwardv along the outer sides of the pedestal jaws 17 as designated by 18, and the corresponding pairs of these flanges 18 are united by vertically disposed flanges 19 with whichlatter are formed integral outwardly projecting and horizontally disposed bottom flanges 20, and outwardly4 projecting horizontally disposed top flanges or ribs 21.

The construction just described provides a substantial and effective reinforcement t0 the'sides and above each journal box open ing.

Formed integral with the depending flange 14 and preferably at'points between the journal box openings are depending brackets 22 which serve as supports for equalizers (not shown) the same being mounted on pins or bolts which pass through apertures 28 formed in said brackets, and alined apertures 24, which latter are formed in the vertical webs 11.

Formed integral with and projecting forwardly from the lower portions of the forward ends of the side frames 10 are rails 25, preferably box-shape in cross section, the same serving as supports for the cylinders of the locomotive which are carried by the bed or frame.

the same serving as a center guide for the usual pony truck (not shown).

The main portions of the frames 10 are connected by transversely disposed separately formed members 29, the same being suitably located and serving as frame filling pieces, and also as points of attachment for the usual expansion plates (not shown),

A which latter support the' locomotive body.

These members 29 which are preferably cast, are of any desired shape in cross section and are secured to the webs l1 of the side frames in any suitable manner, preferably by bolts.

A locomotive bed or frame ofmy im' proved construction combines great strength and rigidity with minimum weight, can be easily and cheaply produced inasmuch as the various parts can be readily cast, and assembled with the expenditure of comparatively little time and labor, and in the event that any part of the frame becomes broken or unfit for service, it cany be readily removed and replaced by a new part without discarding the entire frame, which latter action would be necessary Where the entire bed or frame is cast or formed in a single piece.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved locomo- `tive bed can be made and. substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:

1. A locomotive bed having cast metal side frames, each of which is substantially channel-shape in cross section with its flanges outwardly presented, there being a series of journal box openings formed in the lower portion of each side frame, and a vertically disposed flange on the outer edge of the lower flange of the frame, which vertically disposed flange extends over each journal box opening.

2. A locomotive bed having cast metal side frames, each of which is substantially channel-shape in cross section with its flanges outwardly presented, and vertically disposed flanges on said outwardly'presented flanges.

3. A locomotive bed having cast metal arrears side frames, each comprising a vertically disposed web, horizontal flanges at top and bottom, and vertically disposed flanges on the outer edges of said top and bottom flanges.

4. A locomotive. bed having cast metal side frames, each comprising a vertically disposed web, horizontal flanges at top and bottom, vertically disposed Hanges on the outer edges of' said top and bottom flanges, and the lower portion of each side frame being provided with a series of journal box openings.

5. A locomotive bed having cast metal side frames, 'each comprising a vertically disposed web, horizontal flanges at top and bottom, verticallydisposed flanges on the outer edges of said top and bottom flanges, the lower portion of eachy side frame being provided with a series of journal box openings, and flanges on the frame around said openings.

6. A locomotive bed having cast metal side frames in which are formed journal box openings, vertically disposed flanges on said frames above said openings, and horizontally disposed flanges projecting from said vertically disposed flanges.

7. A locomotive bed having cast metal side frames in which are formed journal box openings, pedestal jaws integral with said side frames adjacent to said openings, ver tically disposed flanges connecting the upper portions of said pedestal jaws, and lhorizontally disposed flanges projecting from said vertically disposed flanges.

8. A locomotive bed having cast metal side frames which are of flanged channelshape in cross section and provided in their lower portions with journal box openings, and flanges on said side frames to the sides of and above said journal box openings.

9. A locomotive bed having cast metal side frames which are of flanged channelshape in cross section and provided in their lower portions with journal box openings,

-vertically disposed flanges lon said frames to the sides of and above said journal box openings, and horizontally disposed flanges on the vertical flanges above said openings.

10. A locomotive bed comprising a pair of separately formed side frames which are of flanged channel section, and separately formed frame members connecting said side frames, certain .of which frame members constitute expansion plate brackets.

11. A locomotive bed comprising separately formed side frames which are sub stantially channel-shape in cross section, transversely disposed frame members connecting said side frames, members integral 'with and extending forwardly from said side frames, which members constitute cyln inder supports, and aseparately formed member connecting the forward portions of said supports, which separately formed member is provided with a pony truck center guide.

12. A locomotive bed havin cast metal side frames in which are forme journal box openings, vertically disposed fianges on said frame to thesides of said openings, a vertically disposedvange connecting the upper portions vof the flanges to the sides of each journal box opening, and a pair of horizontally disposed outwardly projecting flanges on the last mentioned ange'.

13. A locomotive bed having cast metal side frames in which are formed journal box openings, flangeson said frames tovthepsides of said openings, and integrally formed members on the frames above the openings therein, portions of which last mentioned members are substantially channel shape in cross section.

In testimony whereof I hereunto aiix my signature in the presence of two witnesses,

this 21st day of October, 1915.
